Yeah just one bike makes no sense at all. Life is too short for just one bike, i mean i have multiple folding bikes which likely makes no sense whatsoever but to me a 16" wheel feels so different from a 20" and dahon's are a ton of fun. I also agree that it makes no sense to convert a bike from mountain mode to road mode, but a frame that is capable of that excites me. Maybe someone needs to design a bike that goes from road mode to mountain mode as quickly as a folding bike can fold. We would have to call it a transformer bike!!!
